    Abstract: A refrigeration cycle device includes a compressor, a radiator, an air-conditioning heat exchanger, a cooling heat exchanger, an air-conditioning decompression unit, a cooler-unit decompression unit, a refrigerant flow rate detector, and a controller. The radiator is configured to radiate heat of refrigerant discharged from the compressor. The air-conditioning heat exchanger absorbs heat from air to evaporate the refrigerant. The cooling heat exchanger is arranged in parallel with the air-conditioning heat exchanger in the flow of refrigerant. The air-conditioning decompression unit adjusts a decompression amount of the refrigerant flowing into the air-conditioning heat exchanger. The cooler-unit decompression unit adjusts a decompression amount of the refrigerant flowing into the cooling heat exchanger. The controller controls the operation of the cooler-unit decompression unit so that the flow rate of the refrigerant detected by the refrigerant flow rate detector exceeds a predetermined reference flow rate.

    Abstract: A refrigerant cycle device includes a compressor, a radiator, a first expansion valve, a second expansion valve, a first evaporator, a second evaporator, and a controller. The controller is configured to switch between a first evaporator priority control and a second evaporator priority control. During the first evaporator priority control, the controller controls a throttle opening of the second expansion valve based on at least one of a temperature of a first evaporator, a temperature of a refrigerant flowing through the first evaporator, and a temperature of an air having exchanged heat in the first evaporator. During the second evaporator priority mode, the controller controls the throttle opening based on a refrigerant state of the second evaporator. When the at least one of the temperatures is equal to or greater than a switching temperature, the second priority mode is switched to the first priority mode.

    Abstract: A vehicular heat management system includes: a refrigerant circuit; a first heat medium circuit in which a heat medium circulates and exchanges heat with a low-pressure side refrigerant of the refrigerant circuit; a second heat medium circuit in which a heat medium circulates and exchanges heat with a high-pressure side refrigerant of the refrigerant circuit; and a switching device configured to switch a mode between a communicating mode in which the first heat medium circuit and the second heat medium circuit are coupled and a non-communicating mode in which the first heat medium circuit and the second heat medium circuit are not coupled on the basis of a temperature of the heat medium in the first heat medium circuit.

    Abstract: A refrigeration cycle device includes a refrigeration cycle, an outdoor heat exchanger, a cooling necessity determination unit, a determination reference setting unit, and a cooling control unit. The cooling necessity determination unit determines whether or not to cool a battery depending on whether or not a physical quantity that correlates with a temperature of the battery is equal to or more than a predetermined reference physical quantity. The determination reference setting unit sets the reference physical quantity for the cooling necessity determination unit according to the outdoor heat exchanger functioning as a heat absorber or radiator. When the outdoor heat exchanger functions as heat absorber, the determination reference setting unit sets a second reference physical quantity smaller than a first reference physical quantity set when the outdoor heat exchanger functions as radiator.

    Abstract: A first evaporator cools air-conditioning air. A second evaporator cools an object. A first orifice unit and a second orifice unit are capable of changing a refrigerant amount of the first evaporator and the second evaporator, respectively. A control unit controls both the first orifice unit and the second orifice unit so that a temperature of the second evaporator approaches a target temperature. The control unit, in a first mode, performs control not to evaporate a refrigerant at the first evaporator and to evaporate the refrigerant at the second evaporator. The control unit, in a second mode, performs control to evaporate the refrigerant at both the first evaporator and the second evaporator. The control unit sets the target temperature in a first mode higher than that in a second mode.

    Abstract: A refrigeration cycle device includes: a first expansion valve that decompresses a refrigerant flowing out of a high-pressure side heat exchanger; an exterior heat exchanger that exchanges heat between the refrigerant flowing out of the first expansion valve and outside air; a second expansion valve that decompresses the refrigerant flowing out of the exterior heat exchanger; a low-pressure side heat exchanger arranged in series with the exterior heat exchanger; a cooler core that exchanges heat between the heat medium cooled by the low-pressure side heat exchanger and air to be blown into a vehicle interior to cool the air; and a controller configured to switch between a heat absorption mode and a heat dissipation mode by adjusting an amount of decompression in each of the first expansion valve and the second expansion valve.
